ABSTRACT:
A pressure switch is illustrated that includes only three piece parts--two dimpled covers and a spacer. By selecting both the type and thickness of cover materials, switching pressure ranges can be selected to accommodate a very wide range of operating pressures. Fine adjustment of the switching pressure may be made by modifying the cover dimples. Reliability and a hermetic seal is attained through the use of appropriate materials for the covers and spacer, together with active metal braze seals which provide high temperature, moisture and chemical resistance. A vacuum port is added for providing the ability to modify the air pressure within the pressure switch.
